Description

[Detailed Description of the Invention] The present invention relates to a mold for forming concrete products.

For example, in order to form a gutter cover 2 with a plurality of drainage holes 1 from concrete as shown in FIG. A plurality of molding molds 5 fixed on a mold 4 are set in a rectangular formwork 6, concrete is poured into the molding mold 6, and after the concrete has hardened, the molding molds 5 are taken out.

According to the molding die 5 described above, since the plurality of mold blocks 3 are fixed to the mold base plate 4, the mold blocks 3 must be extracted along the axial direction of the mold blocks 3, even if slightly. When it was tilted, the resistance was large and extraction work was difficult. Also,
If the drain hole 1 is removed by force, there are problems such as the opening periphery of the drain hole 1 being chipped.

To solve this problem, the mold block needs to be structured so that it can tilt.To do this, the mold block can be tilted and inserted into the hole provided in the mold substrate, but the mold block and the mold A gap may be formed between the concrete and the substrate 4, and concrete may flow into the gap during molding, resulting in poor molding.

The present invention was developed in view of the above circumstances, and its purpose is to solve the above-mentioned problems by configuring the mold block so that it can move relative to the mold substrate without creating a gap between them. The purpose of the present invention is to provide molds for molding concrete products.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is a perspective view showing an example of the molding die of the present invention, and FIG. 3 is a partially cutaway enlarged view of the main part. In the figure, the same parts as those shown in FIG. 1 are given the same reference numerals, and the explanation thereof will be omitted.

In this embodiment, a mounting hole 4a is formed at the position where each mold block 3 is arranged on the mold base plate 4, and a screw hole 3a is formed in the bottom surface of the mold block 3, and the mold block 3 is fixed with a headed bolt 7. is attached to the mold board 4, but during this attachment, the insertion hole 8 of the headed bolt 7 is
By tightening the headed bolt 7, the elastic body 8 is pressurized by the mold base plate 4 and the mold block 3 via an elastic body 8 made of flat hard rubber having a diameter of 1.

Therefore, although the mold blotter 3 can move without being fixed relative to the mold base plate 4, there is no fear that gaps will be created between the mold block 3 and the elastic body 8 and between the elastic body 8 and the mold base plate 4.

In this embodiment, the mold block 3 is movable relative to the mold base plate 4, so that even if the mold block 3 is slightly tilted with respect to its axis after the concrete has hardened, it can be easily removed without much resistance.

In the above embodiment, the elastic body 8 is interposed between the mold block 3 and the mold substrate 4 in a pressurized state to prevent a gap from occurring, but the invention is not limited to this. 3 and the mold substrate 4 respectively by baking.

As explained above, according to the present invention, a mounting hole is provided at the mold block mounting position on the mold board, a screw hole is provided in the bottom of each mold block, and an insertion hole is provided in the flat elastic body, and the mounting hole is provided at the mold block mounting position on the mold board. Since the head bolt inserted into the hole and the insertion hole of the elastic body is tightened into the screw hole of the mold block, the mold block can be tilted in the direction of removing the concrete product, making it easy to remove the concrete after it hardens. This improves work efficiency.

Further, since no gap is formed between the mold block and the mold substrate, there is no fear that concrete will flow into the gap and cause molding defects.
